Randomized Controlled Trial Comparative Study Clinical TrialRegional anaesthesia for outpatient knee arthroscopy: a randomized clinical comparison of two different anaesthetic techniques.
The purpose of this prospective, randomized study was to evaluate the time required to perform anaesthesia, achieve surgical block and fulfil standardized discharge criteria in outpatients receiving knee arthroscopy with either spinal anaesthesia or combined sciatic-femoral nerve block. ⋯ In patients receiving elective outpatient knee arthroscopy, using a combined sciatic-femoral nerve block with 25 ml of mepivacaine 20 mg ml(-1) and a multiple injection technique results in a slightly longer preoperative time but provides similarly effective anaesthesia with no differences in home discharge times as compared to spinal anaesthesia with 8 mg hyperbaric bupivacaine.

Meta AnalysisNovel analgesic adjuncts for brachial plexus block: a systematic review.
This article reviews current evidence for the efficacy of adding novel analgesic adjuncts to brachial plexus block, the goal of which is to prolong analgesic effect without the disadvantage of systemic side effects or prolonged motor block. It may also allow for a reduction in the total dose of local anesthetic used. Novel adjuncts studied to date include opioids, clonidine, neostigmine, and tramadol. ⋯ Evidence regarding the analgesic benefit of opioid adjuncts remains equivocal and more evidence is required before their routine use can be recommended. Clonidine appears to have significant analgesic benefit and to cause minimal adverse effects when used in doses up to 150 microg. Data regarding other drugs, such as tramadol and neostigmine, are not sufficient to allow for any recommendations, and further studies are required.

Case ReportsComplete brachial plexus palsy after total shoulder arthroplasty done with interscalene block anesthesia.
This report illustrates that brachial plexus palsy can result from either interscalene block or total shoulder arthroplasty. It is often impossible to determine which procedure caused the deficit; therefore, we believe the focus should be placed on treatment of the neurologic deficit. This report provides a suggested algorithm for diagnosis and treatment of postprocedure brachial plexus palsy. ⋯ Proper diagnosis and treatment of postprocedure brachial plexus palsy may improve recovery of function. Several precautions may reduce the likelihood of brachial plexus palsy following interscalene block for total shoulder arthroplasty.
